Question

Write the coefficients of x from these equations :
4/2x-3/2y​

Answer 1

Step-by-step explanation:

4/2 is a coefficient in this equation.

Answer 2

Answer:

Answer

Given 3x

2

−5x+2=0

Here, the coefficient of x

2

is 3 and it is not a perfect square.

∴ Multiply the equation throughout by 3.

⇒(3x

2

−5x+2=0)×3∴9x

2

−15x+6=0

Now, half of the coefficient of x is
